[1.7.10] Placeable Gunpowder Mod Download

Placeable Gunpowder mod lets you place down gunpowder as a fuse for TNT that can be any length: no need for repeaters and redstone.

You can light it with flint and steel or fire arrows, and you can also place it with dispensers. It does a bit of damage to entities standing on it as it goes off. It should work with any modded TNT as well.
